Woofers are  pulsating with a pulse type noise I just connected Orion XTR 2150 with a sealed encloser 2-12" Kicker Comp (Black) 8 ohm. My amp is bridged at 600x1 (4ohm) / subs wired parallel. Any idea what might be wrong (ground maybe) not sure

try regrounding and then try unhooking your rcas from your head unit and see if that stops it...if it does its a source problem. if not im not sure but 2 good places to start i would think.

Also gain is probably too high.

      Is this a timed pulse,  plays for .25 seconds then silent for 2 or 3 seconds?  then it repeats?

What head unit are you using? It sounds like its coming through your rca's.

Ive seen this with the gain too high cause even on silent areas it will pick up the tiniest sound of anything in the rca's Remember nothing is 100percent clean and when you have the gain up high it can pick up on the most impossible little pops and sub frequencies on a cd
I dont care about who has the bigger name in the business... The Bigger the name the Bigger the price. NO BETTER QUALITY!!!

When I move the RCA's from input to Aux the pulsating goes away.

well the AUX should be an input instead of an output.....so your subs shouldnt even work with the rcas plugged into AUX
